' shown and described, as

hvery quickly act v tors, the alternate lmanually movable into inoperative position memb rs 6, leaving the warp perfectly unobstructed in the vicinity oi the-detectors, so that any -ault can be easily and quickly corl rected. The carrier is held in dotted line pol sit-ion by the warp engerv l ing members' 6. lVlie-n the fault is corrected the weaver should return tliearrier to operative osit-ion, but if this should be neglected t ic movement oi' the warp 'itselwill upon the carrier and swing it upward over dead center, so that it will automatically drop down into full-line 'operative osition, Fig. l.

it w be'understood that the automatic positioning of the limiting members is due to the alternate slackening and tightening of the warp, imparting a series of blows upon the eng-aged one oi' the .rods Gand setting up a jumping or rocking movement in the carrier, and as the latter is oi relatively light weight and not far past dead center when in inoperative-position, the movement thus imparted results in a very short time in the automatic positioning ci the device. l

My invention is not restricted tojthe precise construotionfand arrangement herein the same may be modi'ied in various particulars by those skilled in the art 'Without departing fromvk the spirit .and scope of my invention vas set forth in the annexed claims.

Having inlly described my invention, what l claim as new and desire to secure by Letters Patent is':

l. ln a warp stop-motion for looms, in combination, a series of vertically movable detectors each suspended from a single warp thread, and a swinging device to normally limit Vupward movement 'of the detectors,

fing one of the limitl l l l said device being iulcrunied below the warp and manually movable into inoperative position upon the warp back oi' and above the iulcruni, to permit ready access to the detecti glitoning'und slackening oi the 'warp serving to automatically swing` said device past dead center und forward to operative position when the operation of' the loom is resumed.

2. ln a Warp-stop-motion for looms, in combination, a plurality of series of vertically-movable detectors each suspended vfrom a single warp-tliread, a swinging carrier ulcrumed below the warp and provided with a stop member or each series of detectors, and means 'to position the carrier with the stop members above and to limit upward movement ol" the detectors, said ci 'ricr being to permit ready access to the detectors, one oi the stop members-at such time resting l thread, v'fixed supp senses upon the warp back oi' and above the Ilulcruin oi the carrier.

3. ln :i warp-stop-motion for looms, in combination, a plurality of series of vertically-movable detectors each suspended from a single warp-thread, a swinging,l carrier lulc'rumed belovir` the warp and provided with a step member for each series ol detectors, and means to position the carrierL with the stop members beve and to limit upward movement manually movable'into inoperative position' with one of the stop members resting u onv the war i back-oi and above the carrier v`ul' cruin, t ie alternate tightening and slackenof the detectors, said carrier being ing` of the warp acting, and `'means to autoinatically 4return the carrier to operative position when the loom is in operation.

'4.111 `a warp-sto -motion for looms, a pluralityvoi series-or ,vertically movable detectors each suspendedA from a single warports on which the detecoi armslulcrumed at oploom behind the detectors vtransverse stop-rods tors move, a pair posi'te sides 0i 4 the andA below the warps, mountedy on the free ends oi the arms, to normally Aextend above the series of detectors and limit theirupward movement, and rests. to engage and maintain the stop-rods in suoli position, manually to bring one oi' the stop rods into engagement with the w arp and to rest there on wlien'access is to be had to the detectors, the movement of the warp when the loom is in motion acting to automatically swing forward the arms past dead center and position the stop-'rods with relation to the detectors. 5. In a' warp-stopsmotion for looms, in combination, a series of vertically movable detectors each suspended from a single warp-4 thrcad, a swinging carrier pivotally niounte l. behind the detectors and below the warp and movable rearwardly manually `into inoperative position, and means on the carrier to limit upward movement of the detectors when said carrier is operatively positioned,

saidarms being1 swungv rearward said ineens 'rest-ing on the lwarp when the carrier is in its inoperative position, the ac tion of the warp u on said means serving to insure automatical ythereturn of the carrier.
